Application filed Ma 19, 1927. Serial- No. 92,542.

The object of this invention is to provide an incinerator for the disposal of garbage,

- rubbish and other waste material, capable of very economical operation,` and equipped with means ma'king it selftoking 'and for loosening the wet mass of garbag to allow j the hot gases to pass through the same, thus g more quckly evaporating the moisture and allowing more complete and rapid combuso tion.

- Broadly stated, .the invention consists of a Suspended water cooled basket grate to receive and support thewet mass as it is dumped into the inciierator, such basket grate being -formedof sections and movable verticall m its entirety or its sections inde- `pendentl vertically adjustable within the incinerator. i.

Referring to the accompanying drawings, wherein like reference numerals designate corresponding parts throughout the several views, I I

Fig. 3 is a top plan view of Fig; 2,

Fg. 4 s a side elevation of a complete 86 basket grate section, and

Fig. 5 is a top plan view of the two basket grate sections;

` 'In the drawings, reference numerals 2 and- 3 designate the sde wallsof the incinerating I 86 cha'nber proper, between which is located the firing grate 4, stoking ;doors or openings 5 being provided in such walls, and flue open-` ings 6 being provided in the. wall 2 for the escapeof the products of 'combustion to a suitable stack 7. '.'While one form of incinerating chamber is shown in the drawing, more or less diagrammaticallv, it will be understood that other types of furnaces maybe used withoutdeparting from the spirit of 46 the .invention. Fuel for the firing grate 4 may be introducedthrough `the opening 8 in the roof 9 of the incinerator.

i The -garbage or the like is fed through an opening or. door 10 provided in the roof of the incinerator, charging floors 12 flush with the roof 9 of the incinerator, each section be- 5 ing composed of a pair of vertical pipes 18 'having their lower end portions 18' bent in-' wardly toward the adj acent grate section and connected together by a bottom horizontal pipe 19, the endsof which are closed by cleanout plugs 20.` Parallel with the pipe .19 and some distance thereabove is a cross pipe 21, and' between this and the pipe 19 extend a number of vertical parallel pipes 22, these occupying the same curved plane as the bent lower ends 18' of the pipes 18. The upper ends of the pipes 18 each section are connected together by a horizontal pipe 'or reservoir 24, which may or ma not have connection with suitable inlet an outlet means (not shown) for cooling water which circulates through the entire system of grate pipes mentioned. Obviously,=the water which becomes heated in the grate, or its vapor,` may b utilized for any desired purpose. i The vertical pipes 18 are arranged for vertical movement in suitable bearin 26 ro-' vided in the roof 9, and additiona bearngs 28 are' provided for theupper ends of the pipes418, the same' having braces 29 suitably anchored to side walls or other fixed structure' 30. The upper-bearings 28 are connected together by intermediate' braces 31 supporting a platform 32 upon which is arranged suitable Operating mechanism. Various* mechanisms may be employed for raising and lowering the grate basket sections 15 and 16, but for the' purpose of illustrating one suitable mechanism, there is shown a pair of reversin .electric motors M and M mounted on the'p atform 32, and the shaft of each mo tor has a worm gear 42 meshing with a worm gear 43, one of such gears being provided on with pinions 46 meshing with racks 47 pro vided on the pipes 18. The motors have individual switches S and S and individual reversing circuits, there 'being an electric' battery B or other source of current supply.

In operation, firing fuel is -fed through opening 8, or openings, or both onto the firing grate 4 and is there ignited, the products of combustion rising and sweeping across the incinerator chamberandout of orts 6, the basket grate .sections `1 5-and 16 ing located above the firing grate at one' side and in the direct path of such products of combustion, so that the garbage or others refuse which is dumped through the opening.

10 and held in said basketgrate sections and 16 is thoroughly dried and partially consumed thereby. The wet mass of garbage or-refuse will pack of its own weight until the hot gases cannot penetrate the same, and when this occurs, one or the other of the 'switches S S is closed to cause operation of its respective motors M M and the resultant vertical reciproc-ation of its respective basket grate section 15, 16. One motor may not be operated while the other is operated, the .worm gearing of the idle motor serving to check its respective basket grate section from falling of its own weight, or both motors may be reversely Operated to 'se- -cure the desired relative reciprocation between the basket grate sections, which .reciprocation may be fast or slow to suit the desires of the attendant. For' adjusting the general position of the basket grate as a whole according to the height ofthe fuel on the firing. grate 4, both motors may be simultaneously operated. Thus it will be seen that when the mass of garbage or other refuse has become packed, the grate sections 15, 16 may be moved relatively to each other, whether by operation of one or both motors, to permit the hot gases to penetrate the mass and evaporate the moisture therein. When thoroughly dried, the mass of garbag'e or refuse may be dumped onto the firing grate 4 by sufliciently Operating the basket grate sections relatively to each other as` aforesaid.

Obviously, some of the dried mass will fall from the basket grate during drying reciprocation of such' grate sections, but the bulk will be released and dumped as stated. Thus it will be seen that the reciprocation relatively of the basket grate sections not only keeps 7 the mass from packing and admits drying hook-shaped lower ends and being separately able basket.
